When its ?xml:namespace>Norco, Louisiana, plant is fully operational, Diamond Green Diesel will produce 9,300 bbl/day, or 137m gal/year, of renewable diesel that is comparable to petroleum-based diesel and meets low-carbon fuel standards, Darling said in a news release.

No timetable was given for when the plant would reach full operations. A call to Darling International seeking comment was not immediately returned.

According to Diamond Green’s website, the company would like to convert about 11% of US animal fat and used cooking oil into biodiesel.

Darling is a US-based recycler of food and oil products, turning such biomaterial into tallow, feed-grade fats, feed and fuel ingredients for use in fields such as oleochemical and biodiesel production, as well as in agriculture.

US-based Valero is an international refiner of fuels and other petrochemical products.
